It is unsuitable too low to should be noted that solution proportion shared by silica herein and alpha-silicon nitride powders, in case the later period is molten
Liquid is excessive rarefied, cannot achieve good anti-reflective function, and ratio is also unsuitable excessively high, in order to avoid the later period is caused to be difficult to stir evenly,
Therefore need reasonably to control the ratio of powder according to the actual situation.
The volatile solvent can be water either some rate of volatilizations than faster organic solvent, such as methanol,
Ethyl alcohol.
S102, the solution for being mixed with SiO 2 powder and alpha-silicon nitride powders is equably stirred with magnetic bar, is formed
Antireflection solution；
Wherein, magnetic bar plays the role of two in whipping process: being to keep powder abundant with solvent and uniformly mix respectively
With remove the Ferromagnetic Impurities in the mixture, so must during churning periodic cleaning be adsorbed on it is miscellaneous on magnetic bar
Matter not only can improve the uniformity of stirring, and the purity of solution is also improved.
S103, the antireflection solution is equably coated in substrate surface；
Wherein, smearing should be along the same direction, in order to avoid causing to smear unevenly, the thickness of smearing will finally guarantee 1
~5um, it is unsuitable excessively thin or blocked up.
Step S104, the substrate for being coated with the antireflection solution is positioned below under 100 DEG C of environment under low pressure, so that described
Antireflection solution is formed by curing antireflection film in the substrate surface.
It is understood that the homogeneity of solvent volatilization can be improved for the environment under low pressure lower than 100 DEG C for curing environment,
In, temperature can be set to 70 DEG C~90 DEG C, and curing time was at 30 minutes or so.
Such as Fig. 3, above-mentioned SiO 2 powder and alpha-silicon nitride powders are replaced with into niobium pentaoxide, also can use same
Process prepares anti-reflection coating.

S101, evaporated device is provided, places the substrate in heating in evaporated device；
Wherein, substrate, substrate frame and vacuum chamber interior walls should be cleaned in advance, so as not to influence later period film layer purity and
Binding force.
S102, provide PFA organic solution, by the PFA organic solution be placed in the evaporation cavity room of the evaporated device into
Row heat treatment；
It should be noted that must be covered with baffle before PFA organic solution reaches evaporation effect PFA organic solution and
It is other slurry to have been avoided to be splashed on substrate during this period the equipment that substrate pollutes.
S103, the PFA organic solution, which are evaporated, to form PFA molecule deposition in the substrate surface, cold to the PFA molecule
But antireflection film is formed in the substrate surface after.
It is understood that baffle can be taken away by vapor deposition in substrate table after PFA organic solution is begun vaporization
Face, during this period, substrate temperature, plating material evaporating temperature, deposition pressure all affect the effect of vapor deposition, so will be for vapor deposition material
The suitable parameter of material selection.It should be noted that antireflection film is used herein with a thickness of 1~5um after thicknesses of layers reaches requirement
Baffle covers evaporation source and stops heating, but not import air at once.
